HEAT RETAINING AND CONDUCTING ATTACHMENT FOR BURNER STOVES.

Application filed April 30, 1921.

T 0 all whom it may concern:

Be it known that I, MICHEL MAY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in a Heat Retaining and Conducting Attachment for Burner Stoves, of which the following is a specification.

This invention relates to a heat retaining and conducting attachment for burner stoves, of that type provided with burners for utilizing gas, gasoline, oil, or vapor, as a fuel to generate heat for cooking or other purposes, and has for its object to provide in a manner as hereinafter referred to, an attachment for seating on the stove over the burners and including means whereby the heat from one burner can be conducted to one or a plurality of points to be utilized for heating more than one vessel, under such conditions providing for a saving in the consumption of fuel, and to furthermore provide the attachment with means whereby the heat can be retained within one portion thereof so as to be used solely in connection with the heating of a single vessel.

Further objects of the invention are to provide an attachment for the purpose referred to and in a manner as hereinafter set forth, and which is comparatively sim ple in its construction and arrangement, strong, durable, compact, efficient and convenient in its use, readily set up, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as hereinafter more specifically de-, scribed, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings, wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a top plan view, of an attachment in accordance with this invention, with the same extended.

Fig. 2 is a view looking toward the extensible end of the attachment.

Fig. 3 is a side elevation.

Referring to the drawings in detail, a

Serial No. 465,919.

heat retaining and conducting attachment in accordance with this invention, is formed of two sections, one of which is termed a body portion, and the other section an extensible slide. The body portion is formed of a shallow rectangular receptacle including a top wall 7, a pair of imperforate side walls 7 an imperforate end wall 5, an open end 5", and a bottom 6 of less width and of less length than the width and length of the top 7, and which is connected with the side walls 7, end wall 5 and top 7. The side wall 7, and end wall 5 are connected to the lower face of the top 7 inwardly with respect to the side and end edges of said top whereby the latter will project laterally from the said side and end walls. I

The extensible slide is shiftably mounted in the body portion and extends through the open end 5 thereof, andis hollow, as well as shallow, and is formed with an open inner end, a top 15, a bottom 16, which is imperforate, an imperforate outer end wall 1, and a pair of imperforate side walls 1.

The slide is arranged to slide snugly yet freely into one end of the body portion so that, when desired, the opening in the side may be moved into coincidence with an opening in the top 7 of the body so as to register with the same and this opening may have the usual grating used in connection with gas or oil stoves.

The body portion has the top 7 thereof, at a pointbetween its center and the closed end of the body portion, provided with an opening, and the bottom 6 of the body portion is also provided with an opening, the latter registering with the said opening in the top 7. Depending from the bottom 6' of the body portion, is a collar.

Arranged within the body portion and in terposed between the opening in the top 7 ,is av damper capable of retaining heat within the body portion at that part provided with the registering openings, or permitting of the heat to pass into that part of the body portion provided with the other opening and also into the extensible slide.

Vessels can be mounted on the openings in the top 7 and on the opening in the slide, that is to say supported by the top 7 over the two openings in the top and by the slide over the opening in the slide.

The damper is under the control of a handle shown in Fig. 3.

while the burner is active.

' WV hen anything to be heated is placed over the rear opening, it will be so placed that the heat cannot pass out around it and thereby the heat is shut in and forced to pass along the interior of the body portion to the other opening thus conducting the heat and using it twice. v The body portion of the attachment may be of any form desired and is made of any weight of material which will withstand heat suitable for the kind 0]": usedesired. "In Fig. 1, there is indicated a;handle by means of which the slide-may bemoved into and out of the "body portion.

The bottom 16 of the slide has no openingbt-hrough it. y ,v

he general form of the heater is that of a simple heat tight flat-box with 'aflange all around the top edge but not on the bot tom *and having two or more openings through the top or one side-and one open ing only at the bottom or other sideb The material employed in making the instrument is metal, which can withstand heat and of athickness and weight to suitthe purposes for which it is used.

The size of the instrument is in accord ance with the'purpose for which it. is to be used. whether for heavy or for light work.

What is claimed is 2- 1 1. An attachment for the purpose set forth comprising a shallow rectangular re ceptacle including a pair-of side walls, a

' bottom, a top, a closed end wall and an open end, said top provided 'at a point between itstransverse center and each end with an opening, said bottom provided between its transverse center and the vclosed end of the receptacle with an opening arranged below one of the openings in the top, vand ashal low rectangular slide including a pair of side walls, a bottom, a top, a closed outer end wall and an open inner e n,d, said slide mounted in the open innerend' ot said receptacle and permanently communicating therewith, said slide of a length notmore 'thanhalf the length. of said receptacle whereby said receptacle is opened for the inlet of combustion products whenthe slide is completely within the receptacle and. said slidehaving its top. provided with anopening'capable of registering with, oneof the openings in the,top ofthe. receptacle when the slide. is shifted inwardly, the opening in the top of said; s lide providing means for.
